Who would prefer a stock cooler that takes a screw-in replaceable 92mm fan? Or even an option to buy an Intel CPU heatsink that takes a replaceable 92mm fan with heatpipes?
The stock cooler is plenty for 90% of the builds out there. For that last 10% no upgrade is going to help it. Buy a proper aftermarket cooler. Don't try to make the box cooler something that it isn't.
